And "top level" variables count as globals in this respect. If the
'global' declaration above is omitted, runNr still increments over runs.

I think there was a bug in the earlier versions of Tiger, whereby globals
and properties _didn't_ persist. But that's been fixed for a while now.

To "remove garbage from a script between runs", you can set its globals
to less bulky values (eg. "") before it finishes, or, preferably, use
locals instead.
